I don't know anything about your TV, but I haven't seen that old-school type of cable service in YEARS.

So... a few things.

First off, CATV means "cable television." If you see anything saying "CATV", "cable", or "coax", consider it synonymous.

Second, it's possible your TV might not have an analog cable TV tuner in it. Modern TVs don't connect to cable TV service directly; you get a cable box that connects to the cable and then you connect that to the TV using HDMI. The connection on the back that LOOKS like a cable TV connection is meant for connecting either an air TV antenna or things like old video game consoles.

Unfortunately, I don't even know what to recommend at that point. Maybe you could find some ancient TV lying around somewhere, or maybe you can buy a cable TV box compatible with the service on Amazon or something.
